First, I really like this idea for input and think it has potential to 
being very intuitive while allowing a decent input rate.

That said, the screen size (and corresponding button size) is an issue 
to be conscious of.  You want to find the happy medium where you make 
the most efficient use of as little space as possible.  As you make the 
button input area larger, you are taking up more of the application 
area.  But without seeing how this would look on the actual device, it 
at least looks like a good ratio.

That is a question that people will probably have different opinions 
on.  How much effort would it be to have several different layouts.  
Some with more characters, some with less.  Some more similar to qwerty 
other more sequential (abc...) and possibly others mimicking fitaly.  
You could define your default layout as a preference.  And you could 
switch between layouts at any time (possibly via the scroll-wheel or 
other method).

See everybody has their own unique usage requirements.  So lets keep it 
flexible to accommodate the most amount of people possible.

Exactly.  I don't think it would be that hard.  You've got 60deg of area 
for an accurate hit.  Also, having the background of the keys change as 
you are on the key gives great visual feedback.

Again, just showing that different people have different opinions.  Lets 
try to make it useful for everyone.  I would prefer less keys, but that 
is just me.

Heres another thought.  Don't know how it would work/feel, but it might 
give good tactile feedback to give a quick vibration pulse after every 
key press (on the release).  It might help to minimize the disjoint that 
can sometime happen with you are just touching a flat surface.  One step 
further, it might also help if it gave a quick vibration when you 
dragged into different areas.  That way you could tell via touch when 
you were in the different sectors.

Keep the ideas going.  This is one of the best to come out in a while!
